Description

本实用新型涉及一种手动和气动工具。
已有的扭力调整器其前套呈轴空,在该轴空空间内设置具有齿状传动轮及止转槽的传动轴、华司、弹簧、凸键华司和扭力调整环。在前套还设调整槽,以便于扭力调整环的调整,前套上方设牙孔和插销孔,为弹簧、插销和插销螺帽组配,并借护套套置于前套。由于上述组件设置于前套的轴空空间内,尤其是扭力调整环受轴空空间限制,难以提供重力型的扭力调整结构。另外,扭力调整环于前套轴空空间内较难调整。同时,上述组件较复杂,不易装配。
本实用新型的目的旨在提供一种构件简化,组配精确、简便、且可套接套筒使用的重力型手动和气动两用的扭力调整器。
本实用新型包括前套、联动块、传动轴、华司、弹簧、凸键华司、扭力调整环和握柄,前套呈轴空,联动块、传动轴、华司、弹簧和凸键华司设置于前套的轴空空间内,在前套前端延设内螺纹,与联动块的外螺纹螺接固定;联动块前端设套接头,套接头凸伸于前套;扭力调整环螺接于传动轴的外螺纹部并套设于前套上;联动块设嵌接孔,传动轴前端有嵌接轴,传动轴穿设有华司、弹簧、凸键华司。
前套表面设扭力刻度。
传动轴后端设套孔,供旋动握柄套设;另外,扭力调整环上也设套孔,供固定握柄套设。此两握柄可相对旋动,以调整扭力,并可供手动调整使用。
本实用新型比现有的扭力调整器简化了构件,其扭力调整环不再受前套轴空空间的限制,易于精确装配和操作,而且联动块前端的套接头可套接套筒,用于装拆螺帽。另外,传动轴的后端和扭力调整环上均设有套孔,供套设旋动握柄与固定握柄,利用其相对旋动以调整扭力,达到重力型手动与气动两用的目的。
图1为扭力调整器的元件分解图。
图2为扭力调整器的剖视图。
图3为扭力调整器相对旋动操作示意图。
实施例:如图1和图2所示,本实用新型包括前套(1)、联动块(2)、传动轴(3)、华司(4)、弹簧(5)、凸键华司(6)和扭力调整环(7)。前套呈轴空筒形套,联动块、传动轴、华司、弹簧和凸键华司设置于前套的轴空空间内,前套前端延伸内螺纹(11),筒形表面设扭力刻度(12),前套的内螺纹供联动块(2)的外螺纹(21)螺接固定。联动块(2)前端的套接头(22)凸伸于前套(1),该套接头可套接套筒含夹螺帽装拆,联动块后端延伸一盘体(25),盘体端面设钢珠承窝(27),盘体与外螺纹(21)呈颈部,设珠孔(24)供钢珠(23)进入。联动块设轴向嵌接孔(26),为传动轴(3)前端的嵌接轴(36)套置,令嵌接轴(36)设置的钢珠环槽(32)与联动块(2)嵌接孔(26)的珠孔(24)处对置,且于对置处的嵌接孔(26)设钢珠环槽,则钢珠(23)自珠孔(24)进入于两环槽间呈珠环嵌接,珠孔(24)处借扣结环(241)扣结,以防止钢珠(23)自珠孔(24)掉出。
当传动轴(3)的嵌接轴(36)与联动块(2)的嵌接孔(26)互为嵌接时,其嵌接面借钢珠(20)自传动轴(3)的钢珠孔(31)穿设,令钢珠(20)之一端与盘体(25)端面或端面之钢珠承窝(27)接触,钢珠(20)的异端则与华司(4)的端面接触,提供弹性离合功能。传动轴(3)后段设外螺纹部(34)及键沟(33),该后段供华司(4)、弹簧(5)及凸键华司(6)穿设后,为扭力调整环(7)的内螺纹(73)与外螺纹部(34)螺接,令扭力调整环(7)可套设于前套(1),并借前套(1)的扭力刻度(12)指示。凸键华司(6)具凸键(62),嵌设于传动轴(3)的键沟(33),以防止凸键华司的回动,又凸键华司与扭力调整环的接触端面设有钢珠承窝(61),该钢珠承窝对置的扭力调整环接触面则嵌设钢珠(71),则扭力调整环螺设后,借弹簧(5)的弹力,钢珠(20)、(71)使元件间为弹力离合,本调整器的整组构件呈封闭式。
如图3所示,扭力调整环(7)设套孔(72),供固定握柄(8)套设,传动轴(3)的后端也设置套孔(35),供旋动握柄(9)套设。由于本实用新型属重力型,需借两握柄相对旋动,以调整扭力。另外,旋动握柄(9)也可提供手动式调整。
